x freezes after last dapper kernel upgrade

[golfer]

Well, I can now report my third system freeze.  Yes, I am using the
restricted drivers (for nvidia card), and I have installed the headers
and recompiled my modem driver.  Still nothing in the logs .. they
just stop working like everything else, keyboard, mouse, monitor,
sound .. only a hard reboot brings me back.

I'm going to roll my i386 kernel back and run for a day to see if it
stops.  I don't use gnome (except firefox and thunderbird), so don't
think the gnome problems are the culprit.

regards,
